One hint is to look for patterns in which kinds of atoms form substances that conduct when dissolved, and which kinds of atoms form substances that don't conduct when dissolved. Here is a periodic table you can use. Let's start by finding the location on the periodic table for the atoms for substances that conduct when dissolved. What do you notice about where the atoms are?
